Programming :: Including A Space Taken From String In A Var?

Jul 26, 2011

I have a tsv file that I'm trying to break down, line by line, then column by column so to speak. The file is a list of exported usernames, passwords, and display names from an email server, I need each separate to be used in other commands to provision the new server. My problem is, each display name contains a space, as usual with people's names. Here is the script for reference:

Code:

while read line
do
uname=`echo $line | awk '{ print $1 }' >> works`
pass=`echo $line | awk '{ print $2 }' >> works`

Programming :: Grep A String With Space?

Feb 9, 2010

I am using Sun 5.9.

I am putting the value "Feb 10" in variable 'c' here.

Code:
-bash-3.00$ c=`date | awk '{print $2 " " $3}'`
-bash-3.00$ echo $c
Feb 10

But when I am grep-ing value of 'c', I am getting this error.

Code:
-bash-3.00$ ls -lrth | grep $c
grep: can't open 10

This is because there is a space between "Feb" and "10".

Is there any inbuilt function other than strncmp which can evaluate a string.my requirement is " if all 10 values are spaces print 1 else if it contains some values print 2 else print 3.if i use strlen, even space is counted.I know that i can evaluate using for loop by checking 1 by 1 char, and using strcmp function, is there any other way?

Programming :: Pthread - Take String From The Command Line And Creates A Thread To Print The String

May 3, 2011

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.

[Code]....

One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?

Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.

Programming :: C - Put A Specific Arbitrary Part Of A String Into It's Own String?

Apr 18, 2010

So if I'm given a location of a file like:

How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

Programming :: C++: Not #including Files?

Jun 16, 2010

I'm trying to make my program as small as possible. Currently it's down to 17.8 KB, but I'd like to get it smaller (I know, I'm insane). Is there a way to not use the "#include" directive to include the entire header, but rather to just load only the stuff I need? For example, I just want to include 'sprintf' and 'printf' from stdio.h, not the entire header. Is this possible? Or am I misunderstanding some fundamental element here?

Programming :: Including Headers Recursively - Is It Right?

Jul 29, 2010

Say, I have a header file containing all required includes:
Code: /* global.h */
#include <stdio.h>
#include <unistd.h>
...
#include <dirent.h>
#include <signal.h>
... /* and so on */

I have several modules in a program (*.h *.c files) and in each *.h I include global.h, then they are included in corresponding *.c files. And I receive strange messages from compiler, like a "warning: implicit declaration of function fdopendir", "error: expected declaration specifiers or '...' before 'siginfo_t' ", "error: 'DT_DIR' undeclared..." though these types, functions and constants are all declared in system headers. What does it mean?... Compiler is GCC 4.4.4-2, system is Fedora 13 x86_64

Programming :: Sed Strange Behaviour With Line Including Backslash?

Jul 1, 2010

I have a small script that takes input from one file, and uses this input to do a find/replace (with sed) to make an executable snmp trap.The input file could look something like this :JOHBURG SOUTH AFRICAOSLO NORWAY..etcThe script takes the input from this file, and preserves all words in one line as a variable (so that the variables are "JOHBURG SOUTH AFRICA" and "OSLO NORWAY", instead of JOHBURG, SOUTH, AFRICA, OSLO, NORWAY.This is working ok (in the given example, I get two variables).sed is supposed to take this variable, and use it to substitute "HITME" with the new variable.

Programming :: Passing Data Between Kernel Space To User Space In Asynchronous Way

Dec 13, 2010

I am developing a I2C CDROM client driver. The CDROM firmware supports TOC information read through a I2C command. It sends the TOC information in burst ( Interrupts a GPIO pin when it is ready ) and my CPU does a I2C read to read the TOC. When the CDROM firmware finishes sending the last data burst , it informs my CPU that it is done with the TOC, by a flag in the last data burst. I would like to know, which is the most efficinet way I can send these TOC information to userspace?

Programming :: Function In Kernel Space Called Form User Space

Jul 7, 2009

I wanna write a file in kernel space but from my searching I can to know that instead of writeing file in kernel space ,I can write data to user space by copy_to_user space.

But link is missing ...I dont know how will my user space will access kernel space means my function in kernel space which will do copy_to_user /....How my user space function will call my kernel level function ..

Can any one of you provide me with some example file which are doing this .I know every char driver is using it ...but i could not trace back how user level function is accessing it ...i m confused between user space and kernel space.

Programming :: Signal From Kernel Space To User Space?

Jul 21, 2011

I have the following requirement in my module. The driver gets some data from the external device. After getting 1MB of data it has to send it to the user space application. What is the best thing to implement for this in driver.? Is it ok to implement like, after getting data, the driver will send a signal to the user space application. Then the user space application sends an ioctl to read the data. Is there any alternate, that the driver directly sends the data without the user space application asks for it.?

Programming :: Eedirect Stderr To File Including Name Of File With Error

Jul 26, 2010

It's kind of pointless imo for the types of errors that Exiv2 reports on to be written to a text file without some reference to the name of the file that prompted the error message in the first place. Is there a way to have bash identify the file that prompts the error and writes its name to the same file as the error (in my case, frencherrors.TX)?I've tried a painfully simple syntax that does something identical to a 2>&1 'suffix", namely frenchgentsfinder.sh 2 $file>>frencherrors.TX. It makes sense to me as written, but I'd like to know why I'm getting nothing on screen and everything directed to the file when what I want to see in the latter are the filenames causing the errors along with the text of the errors.

Is there another level one has to bore down into before they can garner this kind of output? If so, what is it and how does one invoke it in bash?
